Technical Committee (TC) Intelligent Transport Systems (ITS) Activity Report 2019

Chair: Niels Peter Skov Andersen, Anemone Technology

Developing and maintaining standards, specifications and other deliverables to support the implementation of ITS Service provision for transport networks, vehicles and transport users, including interface aspects and multiple modes of transport and interoperability between systems.

In many respects vehicles on our roads are already connected devices. Very soon they will also interact directly with each other – and with the road infrastructure –  using ‘Co-operative Intelligent Transport Systems’ (C-ITS).

C-ITS allows road users and traffic managers to share and use information and to co-ordinate their actions. As such they are expected to significantly improve road safety, traffic efficiency and the comfort of driving, helping drivers make better-informed decisions and adapt to the traffic situation. Communication between vehicles, infrastructure and other road users can also increase the safety of automated vehicles and their full integration into the overall transportation system.

The first C-ITS vehicles are already appearing on the market. As an illustration of this, in November 2019 car maker Volkswagen announced that its next-generation Golf 8 will feature ITS G5 V2X – developed by ETSI – as standard on all models. Referred to as ‘Car2X’ by VW, this allows vehicles to connect directly with signals from traffic infrastructure and other similarly equipped road users.

Several European Member States are progressing C-ITS deployment activities under real-life conditions through strategic alliances – such as the co-operative corridor that links Rotterdam in The Netherlands to Frankfurt in Germany and Vienna, Austria – as well as the European Union supported C-Roads initiative with EU member states and several non-European Associated members.

In ETSI our ITS Technical Committee (TC ITS) is leading the drive to global standards that will support applications including road safety, traffic control, fleet management and location-based services, driver assistance, hazard warnings and assistance to emergency services. Scope of the committee’s work includes communication media, and associated physical layer, transport layer, network layer, security, lawful intercept and the provision of generic web services. As well as developing standards related to the overall communication architecture, management, security and conformance testing, we are also closely involved in related spectrum requirements for ITS.

During the year TC ITS completed work on the use of existing C-ITS protocols over the LTE-V2X PC5 interface.

See the full list of deliverables published by TC ITS during 2019.

In 2019 we published an update of our Harmonised Standard (EN) on the Basic Transport Protocol (BTP) for geonetworking to incorporate LTE-V2X. Work also progressed on our EN considering geonetworking media-independent functionality.

During the year TC ITS continued its cooperation with TC RT on Road ITS and Urban Rail applications in the 5.9 GHz frequency band. A Technical Report on extension of the 5.9 band for safety related Intelligent Transport Systems (ITS) was published in August 2019.

Interoperability and conformance are key elements in the successful deployment of ITS. During the year TC ITS published a series of test specifications covering ITS V2X use cases in the 5.9 GHz band and conformance testing for ITS security.

The committee also published an update of the Mirrorlink® Technical Specifications (PAS).

TC ITS Working Group 1 (WG1) addresses applications and services for ITS, including requirements from passengers, automotive industry, road network operators; freight/logistics actors and public authorities. In April 2019 new versions of the CAM (Cooperative Awareness basic service) and DENM (Decentralized Environmental Notification basic service) were published. These extend CAM and DENM for the support of LTE-V2X Access Layer, maintaining backward compatibility with ITS-G5 Access Layer. Work was also initiated to update CAM and DENM test specifications.

The group continued to examine the needs of Vulnerable Road Users (VRUs), publishing its first deliverable on VRUs use case definitions in September 2019. Work also progressed on an EN considering position & time function (POTI).

TC ITS WG2 considers overall architecture and cross layer issues relating to ITS. During the year work continued on two Technical Reports linked to C-V2X and potential future radio technologies for V2X, namely:

  • Investigating enhancements to the architecture for communications among ITS stations with multiple access layer technologies
  • Investigating interoperability and backward compatibility when implementing future ITS systems (e.g. C-V2X)

The WG continued to update a TR on the Framework for Public Mobile Networks in Cooperative ITS, taking into account the recent development of mobile network technologies.

In July WG2 published a Service Announcement specification as an EN.

TC ITS WG3 maintained its work on data transport and network protocol aspects of ITS, publishing an update of its EN on geonetworking to incorporate support for LTE-V2X.

TC ITS, WG4 has primary responsibility to encompass ITS standardization on OSI model layers 1 and 2, including the management of these layers. Core WG 4 subject areas currently include:

  • Liaison/participation with regard to TC ERM scoped issues, where WG 4 is the group responsible inside TC ITS for development of ETSI System Reference documents for ITS
  • 5 GHz and 60 GHz spectrum bands
  • Infrared CEN RTTT DSRC
  • ISO CALM (21212 and 21213) 2G/3G

Focusing on security aspects, TC ITS WG5 began revisions of its existing TS on Trust and Privacy Management.

The 6th ITS CMS Security Plugtests event took place during February/March 2019. In December the first C-V2X Plugtests event was conducted in cooperation with 3GPP.

During the year interaction TC ITS maintained its cooperation with other bodies including:

  • IEEE, regarding IEEE 802.11 technology and its evolution
  • ISO (mainly TC 204) for coordination purposes
  • CEN/CENELEC for coordination purposes in the ITS Coordination Group (ITS-CG)
  • EC (CONNECT/GROW/MOVE) in the ITS Coordination Group (ITS-CG)
  • 3GPP for C-V2X technology and its integration into the ITS architecture
